Hello, baby Marxist here!
Personally mine was reading.
When I was a liberal I loathed reading and found it hard to even read a short article. I rarely researched everything I heard, and as a teenager, I was like every other liberal, getting my news off social media.
Now I make sure to research everything, however, getting into theory is a bit hard. Most of the information I learned about communism was through fellow comrades, because like before, I got my information from other people’s comments.
Currently I’m restoring my motivation for reading by starting small. Reading long comments from comrades helped a lot. I’ve now moved on to reading information from leftist sources without effort, and I’m starting on reading the communist manifesto.
Enough about me, what were your side effects?
a side effect for me was that i didn’t look at capitalist media with a critical eye, especially when it was talking about china, north korea, or any other socialist country, or any state that’s against the US (and demonizing them)
